Answer:

12.37 ft

Step-by-step explanation:

Hypotenuse(c): the ladder

Cathetus: the wall (a=12) and the floor (b=3)

Equation:

c^{2} =a^{2} +b^{2}

c^{2} =(12)^{2}+ (3)^{2} =144+9

c^{2} =153

c=\sqrt{153}

c=12.37

The ladder is 12.37 feet long

Hope this helps

A ship traveled for a total of 147 miles over the course of 8 hours. Heading south, the ship traveled at an average speed of 15
Cloud [144]
Alright

s=number of hours headd south
e=number of hours headed east

s+e=8

and
total is 147 miles
distance=speed times time
15s+24e=147


we got 2 equations


s+e=8
15s+24e=147
subsitution

s+e=8
minus e both sides
s=8-e
subsitut 8-e for s in other equaton

15s+24e=147
15(8-e)+24e=147
120-15e+24e=147
120+9e=147
minus 120 both sides
9e=27
divide both isdes by 9
e=3

sub back
s=8-e
s=8-3
s=5

it was headed south 5 miles
